What are code obfuscation and its uses? – What is obfuscation?
An Application obfuscation is the act of hiding a piece of software. Obfuscation also means that it resists reverse engineering, hacking, and other forms of invasion from within an application. The term is often associated with Intellectual Property as an attempt to protect it from theft or destruction.
What is Obfuscation?
Obfuscation typically refers to ways in which complex code is made difficult to understand, with the intention of protecting intellectual property or trade secrets or preventing attackers from understanding the proprietary software.
Encrypting your software’s code is a way to make it more difficult for people to understand what it does. Other approaches you could use include removing any potentially revealing metadata, changing class and variable names with meaningless labels, and adding an irrelevant piece of code somewhere in the program. A tool called obfuscator automatically converts simple source code into a program that works in a similar way and is harder to read or understand.
Unfortunately, malware writers also use these methods to prevent their attack mechanism from being detected by anti-malware tools. Here are some other examples of hackers using these techniques.
Decryption techniques can be used to reverse engineer or undo code. They include program slicing, which narrows down the program to only relevant statements. Compiler optimization entails making a program more efficient and program synthesis entails making it more understandable and easier to use. Obfuscation makes reverse engineering impossible without the algorithm being modified.
